UNIT 7 EQUILIBRIUM
Equilibrium is a state where the rate of evaporation is equal to the rate of condensation.
The mixture of reactants and products in the equilibrium state is called an equilibrium mixture. When there is no change in the concentration s of either of the reactants or the products, the stage is called dynamic equilibrium. At dynamic equilibrium, the rates of forward and backward reaction become equal.
GENERAL CHARACTERISTICS OF EQUILIBRIA INVOLVING PHYSICAL PROCESSES
For physical processes, the following characteristics are common to the system at equilibrium:
LAW OF CHEMICAL EQUILIBRIUM
At a given temperature, the product of concentrations of the reaction products raised to the respective stoichiometric coefficient in the balanced chemical equation divided by the product of concentrations of the reactants raised to their individual stoichiometric coefficients has a constant value. This is known as the Law of chemical equilibrium or Equilibrium law.
APPLICATIONS OF EQUILIBRIUM CONSTANNTS
The important features of equilibrium constants are:
